I just bought a 2000 Blazer 4wd at an auction. It has 97k on it and i had to have the transmission rebuilt. After that, the only problem i notice is the fuel gauge doesnt seem to be working correctly. it works fine from a full tank to a half a tank, but then doesnt go anywere. The other day on a road trip the gauge read half a tank but I had driven 190 miles. Any help you guys could give me would be great. Thanks
